Like I said, I'd like to start with our fundamental CRUD endpoints. Before we write any API-specific code we should be aware of versioning. Like in other applications there will be improvements, new features, and stuff like that. After that we'll be extending the API with each best practice. Now we should be ready to create a basic setup for our API.
Best Practices in API Design
This explains the API queries for all pens in the stationery database. Good API design improves the usability of your API, resulting in higher adoption, less headaches, and an overall better chance of success for your API endeavors. While I’ve laid out the importance of API design, putting this is practice can be hard. In my upcoming blog posts, I will try to lay out some good practices while designing your API. 2 “Understanding the API-First Approach to Building Products.” Swagger.io, 2021, swagger.io/resources/articles/adopting-an-api-first-approach/. With the addition of API design tools to RapidAPI, stay tuned for more tutorials focused on API design.
Step 2: Define the API contract with a specification
As the codebase grows, you may want to concurrently run tests with real data and those known good data sets, but be sure to isolate those test runs with segmented data. JavaScript Object Notation (JSON), is the de facto standard for REST APIs. An organization that widely uses Microsoft technologies might opt to use Simple Object Access Protocol (SOAP), which supports the Web Services Description Language (WSDL). If you point your client application to a WSDL file, you can write code against the API almost as if it were a code library. In essence, filter implements search, while sort allows the query to change the order preference. These are two of the most common features in e-commerce, or in any database.
Differences between OpenAPI 2.0 and 3.0
We can extend this object the more filter parameters we'd like to accept. If we try to add a new workout but forget to provide the "mode" property in our request body, we should see the error message along with the 400 HTTP error code. That's the reason why it's always a good practice to return proper HTTP error codes for different cases.
The first step in designing a REST API-based application is identifying the objects that will be presented as resources. So based on the business requirements API development team first start describing API designs as an Open API document and collaborate with the stakeholders to gather feedback. Facebook’s API is not developer-friendly, and with frequent updates, their product deprecates and becomes even more complicated for hackers. Still, even though it was a welcome experience, users did not receive the faster speeds expected, especially those who consume many resources through the API. Years back, the standard APIs were SOAP; nowadays, the most popular design style is REST, a resource-based design architecture. Representational State Transfer (REST) was a proposal from Roy Fielding, independent of any underlying protocol.
What are common API architectures?
Whereas companies that take a code-first approach might view APIs as afterthoughts, API-first companies design their APIs before they develop their applications. This strategy enables consumers and producers to collaborate on API definitions before the implementations are built out, which improves both the quality and usability of APIs. Once you have a firm grasp on creating and managing API routes within Next.js, the next step is to integrate these routes with other services and APIs. This could include connecting to databases, interfacing with external APIs, and securely managing configuration through environment variables.
Best practices are informed by principles and often change over time. Therefore, when designing APIs, remember that principles have seniority over best practices, but the best practices help you understand and abide by the principles. For example, it’s considered best practice—when developing the next software version—to tag your Git commits with the next version number (i.e., v2.0.0). Then, after the release, the repository changes are easily found and included in release notes.
Use nouns instead of verbs in endpoint paths
The same principle also applies to the POST, PUT, and DELETE endpoints. They can all use the same kind of nesting structure for the path names. REST APIs are one of the most common kinds of web interfaces available today. They allow various clients including browser apps to communicate with services via the REST API.

A resource that would play an important role in the API is the user model. Additionally, if we also had a pet data model, we can expect to build the API around the two models, user and pet. When you look at the top of our comment under "tags", you can see that I've added another key called "parameters", where I've defined our query parameter for filtering. Those comments that are inside your codebase are also a great documentation for yourself as the API developer, too.
The REST API design allows various users to communicate with a server through the API. Apart from RESTful design, there are other architectural designs such as GraphQL. With the actions for our order endpoints fleshed out, the final step is to decide what data needs to be exchanged between the client and the server. Borrowing from our pizza parlor example in Chapter 3, we can say that an order needs a crust and toppings. We also need to select a data format that the client and server can use to pass this information back and forth.
HATEOAS does increase flexibility by making versioning and documentation easier, however, in API design, many questions must be considered. An organization that has unique data could take advantage of this resource by allowing access to the data via API. Unique content, data, and services can make access to the API extremely valuable. Another common misconception is believing that for an API to be valuable users must be prepared to pay for it. APIs are usually driving some other metric—sales, affiliate referrals, brand awareness, etc. The value of the API to users is the result of an API call (service request and response), rather than the call itself.
Go through the article and learn new tools that will give you knowledge about the API design and connectivity of the front end and back end. Similar to device collection representation, create configuration collection representation with only minimal information. Note that both objects/resources in our above model will have a unique identifier, which is the integer id property. In the next chapter, we explore ways to make the client react to changes on the server in real time. Business is so good, in fact, we decide we want to start tracking orders by customer to gauge loyalty. To get a feel for how a company would design an API, let's try our hand at it with our pizza parlor.
Armed with an understanding of your use cases, you’re ready to begin your API design. Each project is different, so API design best practices may not always fit your situation. However, these are guidelines to keep in mind as you design your API. When you involve others in API design, you build something better.
